Description

The present invention relates to shoes worn on bare feet when performing sports such as running, and particularly to a device for preventing slippage between bare feet and shoes.

As a technique for preventing an adherend such as shoes or socks to be attached to bare feet from slipping between bare feet, for example, Patent Document 1 describes a technique for directly applying a non-slip agent such as an adhesive to the surface of an adherend. Is disclosed. On the other hand, Patent Document 2 discloses a technique of attaching a non-slip sheet to both the front and back surfaces of the insole in order to give the insole, which is separate from the shoe, a non-slip function. Further, Patent Document 3 discloses a technique of interposing a double-sided adhesive tape between socks and bare feet.

Now, if the adhesive is applied directly to the inner surface of sports shoes, it is possible to easily prevent slipping with bare feet. However, if the anti-slip function deteriorates due to the frequency of use, a problem arises in the method of reproducing the function. In addition, it is not possible to deal with the case where the anti-slip function is not used temporarily, that is, when it becomes necessary to stop.

On the other hand, the inlay can be detachably attached to the insole of sports shoes, so if you attach non-slip sheets to both the front and back of this insole, the anti-slip function will deteriorate and you can select the function. It can be easily dealt with. However, in many cases, it is not always necessary to provide anti-slip protection on the entire sole surface. For example, when running, it may be necessary to provide non-slip to the toe area of the sole in order to efficiently transmit the kick force to the field through the shoe, but the soil on the sole of the foot Since the arched region does not land as a whole and the arched curve is greatly deformed, it is considered unnecessary to provide anti-slip. That is, it is possible to specify a region that is effective for running by applying anti-slip on the surface of the foot including the sole and the instep. In other sports as well, areas peculiar to that sport can be considered.

Therefore, the subject of this invention is to attach and detach the anti-slip member in an effective region for preventing the bare foot from slipping on the inner surface of the shoe.

In order to solve the above problems, the present invention is based on a sports shoe having a sole and an outer cover fixed to the periphery of the sole, the flat surface corresponding to at least the toe of the insole of the sole. The non-slip area is divided into arbitrary shapes in the region, and a sheet-like non-slip member having a flat shape substantially the same as the non-slip area and having adhesive layers on both the front and back surfaces is detachably attached.

It is preferable to form the non-slip area as a depression having a depth of about 0.1 mm to 2 mm. Further, it is preferable to form it on a flat surface having an average roughness Rz of 200 μm or less. Further, when the non-slip area is provided on the outer cover, a through window can be provided in the area.

The non-slip device for sports shoes according to the present invention includes a flat non-slip area defined on the inner surface of the insole or outer cover of the sole of the sports shoe corresponding to a part of the surface of the foot, and this area. It is composed of a sheet-like non-slip member having substantially the same planar shape and having adhesive layers on the front and back surfaces. It adheres to the non-slip area and is removable.

The non-slip area is preferably a recess having a depth of about 0.1 mm to 2 mm. Further, the non-slip aria is preferably formed on a flat surface having an average roughness Rz of 200 μm or less. Further, when a non-slip area is provided on the outer cover of the sports shoes, a through window can be provided inside the outer circumference of the area at regular intervals.

According to this device, depending on the type of sport, an area that is particularly effective in preventing shoes from slipping can be arbitrarily selected and defined in an effective shape, and slipping can be performed when cleaning or repairing shoes. It can be done by removing the stopper member, and even if the anti-slip member deteriorates, it is easy to replace and the cost is low.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. As shown in FIGS. 1 and 2, the sports shoe 10 includes a sole 20 and an outer cover 30, and the sole 20 is composed of an outsole 21 in contact with the field or the floor surface and an insole 22 in contact with the sole of the foot. The outer peripheral edge of 30 is joined to the outer peripheral edge of the shoe sole 20, and the inner peripheral edge is opened in a keyhole shape to form a shoe opening 30a. By inserting the foot through the opening 30a and tightening the shoe strap 30b, the outer cover 30 is brought into close contact with the instep, and the shoe 10 is attached to the foot. As will be described later, a removable insole can be attached to the inner surface of the insole 22. Further, spikes, studs, points, heel plates, blades, dimples (dents) and the like are provided on the bottom surface of the outsole 21 as needed.

On the surface of the insole 22 (the surface in contact with the sole of the foot), a non-slip flat region is defined along the waviness of the surface. For example, as shown in FIG. 3, the toe region 23, the arch tip region 24, and the heel region 25 are defined corresponding to each of the lower surface of the toe of the foot, the tip of the arch, and the heel. These areas 23 to 25 are areas where the sole of the foot is particularly strongly pressed against the field or the floor surface via the shoes 10 when training is performed, for example. These regions 23 to 25 are examples, and the shape range of the plane region is naturally different depending on the type of sport, and the position and number may be different.

Further, a non-slip region can be provided on the inner surface of the outer cover 30. For example, as shown in FIG. 4, a toe region 31 is provided substantially corresponding to the lateral surface of the basal bone of the toe of the foot. A window 31a penetrating the outer cover 30 can be provided in the mother toe region 31. In this case, an annular band 31b having a constant width is provided between the outer peripheral edge of the window 31a and the outer peripheral edge of the toe region 31. In addition to this, the heel side surface area 32, the instep area 33 corresponding to the instep, and the like can be provided corresponding to the inner surface of the heel of the foot. Of course, windows can also be provided in these areas 32 and 33. As described above, these areas 31, 32 and 33 are examples, and the shape range, position, and number can be arbitrarily selected. Therefore, a non-slip region can be provided corresponding to the proximal phalanx of the small toe and the lateral surface of the heel.

If the above areas 23 to 25 and areas 31 to 33 are collectively referred to as a non-slip area 40, the areas 40 may be divided by colored lines or the entire area may be colored so that the areas 40 can be clearly seen. It is advisable to provide signs such as ridges and grooves. Further, as shown in FIG. 6A, this area 40 is preferably formed as a recess 41 depressed from the surface of the insole 22 or the inner surface of the outer cover 30. The depth D of the recess 41 is about 0.1 to 10 mm, preferably 0.1 to 2 mm. The bottom surface 42 of the recess 41 is preferably appropriately flat. For example, the average roughness Rz is about 500 μm or less (reference length 8 mm), preferably 200 μm or less. Of course, the planar shape of the recess 41 is the same as that of the individual regions 23 to 25, 31 to 33. In the case of the region 31 provided with the window 31a shown in FIG. 5, as shown in FIG. 6B, the annular bottom surface 42a (31b, 31b) having a constant width inward from the outer circumference of the region 31 formed by the peripheral edge of the recess 41. FIG. 5) is provided to form the through window 31a.

A non-slip member 50 as shown in FIG. 7 is attached to the recess 41. As shown in FIG. 7A, the non-slip member 50 is a sheet-like material in which the pressure-sensitive adhesive layers 52 and 53 are provided on both surfaces of the flexible base material 51. Further, as shown in FIGS. 7B and 7C, the non-slip member 50a used in the region 31 having the window 31a has an adhesive layer 52 on one surface of the base material 51 and an annular adhesive on the other surface. Layer 53a is formed. The cyclic pressure-sensitive adhesive layer 53a corresponds to the annular band 31b (FIG. 5) of the region 31.

As the flexible base material 51 of the non-slip member 50, a single body or a laminated body such as a woven cloth, a non-woven cloth, a knitted cloth, or a synthetic resin film is used. As the pressure-sensitive adhesive layers 52, 53, 53a, acrylic-based, polyester-based, and silicon-based pressure-sensitive adhesives are suitable, but a pressure-sensitive adhesive having a particularly large shear stress at the pressure-bonding interface and being easily peeled off is selected. A polyester adhesive is preferable from this point of view. The pressure-sensitive adhesive layers 52, 53, and 53a may be formed by coating the entire surface, or may be formed by a part coat having a dot shape or a grid shape.

As shown in FIG. 8, the non-slip members 50 and 50a are attached so that the peripheral edges are adapted to the recess 41 of the non-slip area 40. In the case of the non-slip member 50, as shown in FIG. 8A, the other pressure-sensitive adhesive layer 53 is crimped to the bottom surface 42 of the recess 41 whose surface roughness is adjusted as described above, and the other pressure-sensitive adhesive layer 52 is pressed. Is exposed entirely from the insole 20 or the jacket 30. Therefore, it is preferable to adjust the depth D of the recess 41 (FIG. 6) so that the total thickness of the base material 51 of the non-slip member 50 and the other adhesive layer 53 is substantially equal. The case where the other pressure-sensitive adhesive layer 53a is cyclic is shown in FIG. 8 (B). As shown, the annular pressure-sensitive adhesive layer 53a is pressure-bonded to the annular bottom surface 42a (FIG. 6B) of the recess 41. Then, the window 31a is closed by the base material 51.

As described above, when the sports shoes 10 having the non-slip members 50 and 50a attached to the non-slip area 40 are attached to the bare feet, the adhesive layer 52 on the outer surface of the non-slip members 50 and 50a comes into close contact with the skin of the bare feet. Now, when the running surface is strongly kicked up by the toe of the foot during running, the non-slip member 50 interposed between the toe region 23 (FIG. 3) of the insole 22 and the bare foot receives a strong compressive force. One of the adhesive layers 52 exerts an anti-slip effect with the bare feet due to its adhesive force, and the other adhesive layer 53 also exerts an anti-slip effect with the insole 22. As a result, the bare feet to the soles of the shoes. The kick force is integrally transmitted to the 20 to enable efficient running. In addition, the most effective location, area, shape, etc. for providing the non-slip area 40 can be arbitrarily selected according to the type of sport, such as a sport that requires a sharp turn or a ball kick, and is suitable for that sport. It is possible to manufacture sports shoes that have been made, and it is also possible to provide custom-made sports shoes.

Since the anti-slip members 50 and 50a are removable, they may be removed when cleaning the shoes 10. Of course, if the anti-slip members 50 and 50a deteriorate, they can be replaced. In this case, a sheet-like member to which the release paper is attached to both sides of the anti-slip members 50 and 50a is prepared, cut according to the shape of the anti-slip area 40, and then the release paper is peeled off for use. be able to.

As described above, a removable insole can be stacked on the upper surface of the insole 22. This insole is formed to have substantially the same shape as the insole 22, and is preferably used integrally with the insole 22. In this case, the insole is provided with a non-slip area similar to the toe area 23, the arch tip area 24, the heel area 25, etc. as shown in FIG. The non-slip member 50 may be attached to this area and the insole may be inserted into the insole 22.

The sports shoes of this invention can be used not only for so-called sports but also for shoes for jogging and rehabilitation. Further, the outer cover 30 is not limited to the one that covers the entire surface of the foot, but can also be applied to the one that partially covers the toe portion and the instep of the foot, for example.
